在本文中，我们提出了一种可以引起振动的装置，可以加速正畸牙齿移动的速度，从而缩短正畸治疗的持续时间。这是通过谐波激励聚偏二氟乙烯 (PVDF) 压电执行器产生振动从而产生 30 Hz 的循环负载来实现的。 PVDF 因其高柔韧性、生物相容性和低成本而成为一种流行的压电聚合物。一般来说，应用循环负载（振动）可以逆转骨质流失、刺激骨量、诱导颅骨生长并加速牙齿移动。这减少了与正畸治疗相关的疼痛体验和不适，并提高了患者对治疗的依从性。与药物治疗相比，振动的优点是副作用最小。该设备连接到定位器或牙齿矫正器。这项工作的主要优点是该装置可以在牙齿矫正器的不同位置进行调整和重新定位。我们提出了一种设备，它结合了振动、谐波函数生成以及电池和处理器的外壳单元。目前的方法需要外部设备，这对患者来说相对麻烦。基于分布参数模型的理论分析被用来证明我们的主张。使用有限元分析模拟压电驱动行为。
In this paper, we propose a device that can induce vibration to potentially accelerate the rate of orthodontic tooth movement and thus reduce the duration of the orthodontic treatment. This is accomplished by harmonically exciting a polyvinylidene fluoride (PVDF) piezoelectric actuators to generate vibration and hence generate cyclic loading at 30 Hz. PVDF is a popular piezoelectric polymer because of its high flexibility, biocompatibility, and low cost. Generally, application of cyclic loading (vibration) reverses bone loss, stimulates bone mass, induces cranial growth, and accelerates tooth movement. This reduce the pain experience and discomfort associated with the orthodontic treatment and also enhances the patient compliance with the treatment. Vibration has the advantage of minimal side effects in comparison to medicinal treatments. The device is attached to either a positioner or teeth aligner. The main advantage of this work is that the device can be adjusted and repositioned in a different location of the teeth aligner. We propose one device that incorporates vibration, harmonic function generation, and the housing unit for the battery and processor. Current approaches require an external device, which is relatively cumbersome to the patient. Theoretical analysis based on the distributed parameter model is utilized to justify our claim. Piezoelectric actuation behavior is simulated using Finite Element Analysis.
